High Gain Modified Quadratic Boost-Cuk Converter with L-Impedance Network for Fuel Cell Application

Fuels cells (FC) are becoming the need of the hour for electric vehicles (EVs) in recent generation as they are echo friendly in nature. For operation fuel cells look for efficient DC-DC boost converters with wider range of voltage gain as FC possess low voltage. The FC cell with DC link and energy storage devices as super capacitor and batteries proves more reliable system for EVs. Selection of the converter to operate in synchronization with fuel cell is an important aspect today. Here, a high gain modified quadratic Boost-Cuk DC-DC converter with L-impedance network (L-impedance QBCC) is proposed as per the suitability. The L-impedance QBCC consists of quadratic Boost-Cuk converter along with L-impedance network with the benefits of more voltage gain. It lessens power switch voltage stress as it did in the existing circuit Hybrid Quadratic Boost-Cuk Converter(HQBC). A detailed analysis is done in order to derive the equation for the proposed high gain L-impedance QBCC and developed the circuit. The detailed analysis of the L-impedance QBCC with working modes is presented. In the model, the modification in the paper work has been highlighted and the results have been verified using Matlab simulation. The proposed L-impedance QBCC is designed for 400 Watt and the results are considered for the steady state.
